WATCHGASE.

Application med April 88, 1922. Serial Io. 557,187.

To all whom it may concern: e

Be it known that I, Max seine, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Watch cases, of which the following is a specifics. tion.

This invention relates to watch eases, particularly to that type worn upon the wrist, the main object being the provision of a case comprising three members, one of which carries the watch movement and is entirely removable from the remaining elements. v

Another object is to provide a watch case having a movement carrier which can he secured to either side of the case so that the face of the movement, with which one is interested, may be exposed without the necessity of removing the watch movement from the case.

These and other objects will become apparent in the description below 111 which similar characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing; Figure 1 is a top plan view of a watch case show in the dial mounted therein.

Figure 2 is a cross-sectional view rthrii the watch case, taken on line Q2 of Figure 1 and shows the case members separated with the movement carrier in place in the lower element.

Figure 3 is a similar section taken on line 3-3 of Figure 1 and shows the movement carrier in place on the upper member.

Figure 4 is a perspective view of the cas in open position.

Figure 5 is a perspective view of the movement carrier shown in proper relation to Figure 4 for its insertion into the easd Jescrihing the drawing in detail, the nu= meral indicates the back cover member havin side walls 11 extending upwardly there om around its entire edge and is provided with a hollow hinge sleeve 12 formed integral on the upper edge of one of the end walls.

An open face casing 13 of the same. pro portion as the back cover has a air oi" hinge sleeves 14 into I with the side corresponding to the hinge wall of the hack cover member 10, spaced so as to receive the hinge sleeve 12 therehetween. Said hinge sleeves 12 and 14, when aligned with each other, receive a in e pin 15 which secures the back cover 10 slid the casingl3 in hinged relation to each other. Said hinge sleeves are formed on hoth the casing and back cover in such manner as to have portions of their peripheries pro'ect into the casing. The upper portion 0 said casing 13 has inclined sides which are formed into a ledge 16 receptive of a. transparent glass or crystal 1? rmanently secured in place by hezelling t e ed 18 over the glass. e The end walls 0 said casin 13 have bar yokes 19 attached thereto an to which the common type of wrist band is secured so as to enable a person to wear the device iipon the wrist in a well-known manner.

A movement carrier 20 composed of all sectionsof similar contour to the back cover and easing, forms a hollow frame close fitting the casing and cover and in which a watch movement or mechanism is mounted, the same not being shown so as to simplify the illustration'of the device. Obviously the movement when retained in place within the carrier will have both its upper and lower surface 6 osed for inspection or repair. The'end wa l 22 of said carrier 20 is provided with a channel 21 semi-circular in outline to register with that portion of the hinge sleeves projecting within the casing. The opposing end wall 23 has a rib 24 thruout its length and when in place within the casing projects from one end between the casing elements.

It is to he understood that the materia of which the casing, back cover and movement carrier are formed has a high degree oi? inherent resiliency so that the various members can he retained in closed relation Toy having one edge or surface rest upon another under a constant spring tension.

This case is designed primarily to remedy some of the trouhles attendant to repair and assembly oi watch. By having the movement mounted in a separate carrier, such as 20, can he seen that the same can he removed from the casing without disturbing any oi the parts and at the same time expose the entire mechanism to view. If the rear side of the movement is to he exposed the carrier 2@ is retained in the casing 13 and the back cover is swung open. This is shown by Figure 3. When the u per face of the movement is to he expose the carrier 20 is retained in the back cover 10 as illustrated in Figure 2. In both ,cases the internally projecting portions of hinge sleeves 12 and 14 engage in the'channel 21 of carrier 20 and releasably retain the latter in either the casing or the back cover. Figure 5 shows the carrier 20 in its proper relation to the casing (as illustrated in Figure 4? when it is to be inserted in place.

I c aim;

A watch case comprising a substantially rectan ular casing having angular corners, a simi ar open faced cover ingedly connected to said casing, the hinge sleeves of both members projecting partly into the casing chamber, a carrier frame receptive of a watch movement being adapted to telesco e into the casing and cover members, sai carrier frame havin a channel which receives the said inward y projecting portion of the bin e, said channel being ada ted to retain t e carrier frame remova 1y secure in either the casin or cover memher, a longitudinal'rib on t e carrier frame on the side opposite to the channel and projecting outwardly between the cover and casmg, said rib being adapted to retain the carrier frame in te escoped position in either the casing or the coverwhen said casing and cover are opened. I

In witness whereof I aflix mg si ature.
